Dab tsi yog methyl tin stabilizer?

Methyl tinCov tshuaj stabilizers yog ib hom organotin compound uas feem ntau siv los ua cov tshuaj stabilizers thaum tsim cov polyvinyl chloride (PVC) thiab lwm yam vinyl polymers. Cov tshuaj stabilizers no pab tiv thaiv lossis txo qhov thermal degradation ntawm PVC thaum lub sijhawm ua thiab siv, yog li ua kom cov khoom siv ruaj khov thiab ua tau zoo. Nov yog cov ntsiab lus tseem ceeb txog methyl tin stabilizers:

Cov Qauv Tshuaj:Cov tshuaj Methyl tin stabilizers yog cov tshuaj organotin uas muaj cov pawg methyl (-CH3). Piv txwv li suav nrog methyl tin mercaptides thiab methyl tin carboxylates.

Kev Tswj Xyuas Kom Ruaj Kho:Cov stabilizers no ua haujlwm los ntawm kev sib cuam tshuam nrog cov chlorine atoms uas tso tawm thaum lub sijhawm PVC thermal degradation. Cov methyl tin stabilizers neutralize cov chlorine radicals no, tiv thaiv lawv los ntawm kev pib ua kom muaj kev puas tsuaj ntxiv.

Cov ntawv thov:Cov tshuaj methyl tin stabilizers siv dav hauv ntau yam kev siv PVC, suav nrog cov kav dej, cov khoom siv, cov ntaub ntawv profile, cov xov hlau, thiab cov yeeb yaj kiab. Lawv ua haujlwm tau zoo tshwj xeeb hauv cov xwm txheej ua haujlwm kub siab, xws li cov uas ntsib thaum lub sijhawm extrusion lossis txhaj tshuaj molding.

Cov txiaj ntsig:

Kev Ruaj Ntseg Thermal Siab:Methyl tin stabilizers muab kev ruaj khov thermal zoo, tso cai rau PVC kom tiv taus qhov kub siab thaum lub sijhawm ua tiav.

Kev Khaws Xim Zoo:Lawv pab txhawb kom muaj kev ruaj khov ntawm cov xim ntawm PVC cov khoom los ntawm kev txo qis kev hloov pauv los ntawm kev kub hnyiab.

Kev Tiv Thaiv Kub Zoo heev:Cov tshuaj methyl tin stabilizers pab cov khoom PVC tiv taus kev puas tsuaj dhau sijhawm thaum raug cua sov thiab tej yam kev mob ib puag ncig.

Cov Kev Xav Txog Kev Cai Lij Choj:Txawm hais tias siv tau zoo los xij, kev siv cov tshuaj organotin, suav nrog cov tshuaj methyl tin stabilizers, tau raug kev tshuaj xyuas los ntawm cov koom haum tswj hwm vim muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv uas cuam tshuam nrog cov tshuaj tin. Hauv qee thaj chaw, kev txwv lossis kev txwv tsis pub siv cov tshuaj organotin stabilizers tau raug tsim.

Lwm txoj hauv kev:Vim muaj kev hloov pauv ntawm txoj cai, kev lag luam PVC tau tshawb nrhiav lwm yam tshuaj stabilizers uas txo qhov cuam tshuam rau ib puag ncig. Cov tshuaj stabilizers uas muaj calcium thiab lwm yam tshuaj uas tsis yog tin tau siv ntau zuj zus los teb rau cov cai uas hloov pauv tas li.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kev cai lij choj yuav txawv ntawm thaj chaw, thiab cov neeg siv yuav tsum ua raws li cov kev cai hauv zos thiab cov lus qhia thaum xaiv thiab sivCov khoom siv PVC stabilizerIb txwm sab laj nrog cov neeg muag khoom, cov lus qhia hauv kev lag luam, thiab cov tub ceev xwm tswj hwm kom tau cov ntaub ntawv tshiab tshaj plaws txog cov kev xaiv stabilizer thiab kev ua raws li txoj cai.
